American actress Lindsay Lohan has scored high marks for her professionalism on the sets of her new movie Labor Pains.

Producers were not really eager to work with her, but after seeing her behavior they have only praise for the young actress. "We were a little bit reluctant to work with her," People mag quoted Lati Grobman, one of the producers, as saying. "But she's been amazing," she added.

It looks like Lohan is trying to get her acting career back on track ever since she showed up for work on June 9 at the L.A. location, coming to work early and being well prepared for the gruelling 12-hour shooting days.

In the new comedy, Lohan plays a publishing house employee who escapes getting fired by pretending to be pregnant. "She's so natural at what she does. I've never seen one take where she's off," Grobman said. "The difference between her and the other girls that are naughty in the business is that she's actually talented. It's not [like] Paris Hilton and the rest of them. We took the chance. It's good that we did. So far, so good," she stated.

The only problem marring the work, are the horde of photographers who have infiltrated the Los Angeles-area locations.

"Paparazzi are ruining my life," Grobman revealed.

"This is the most insane thing I've ever seen in my life. They do things that are very, very aggressive. I'm not a producer anymore, I'm a police woman," she ended.
